5. April 2016: CernVM-FS 2.2

Update 26. May 2016: CernVM-FS 2.2.3

Bug fix version CernVM-FS 2.2.3 released. This version incorporates fixes from version 2.2.2 as well. Please find the list of fixed bugs in our technicaldocumentation.

CernVM-FS version 2.2.1 is out! Version 2.2 contains a number of improvements and bugfixes. Please find detailed release notes in our technical documentation.

Substential improvements in this release are:

Move to semantic versioning. Bugfix releases to this release will be named 2.2.Z with an increasing value for Z. In parallel, we will work on feature release cvmfs version 2.3.

Support for Overlay-FS on the release manager machine as an alternative to aufs. Please note that Overlay-FS on RHEL 7 is unfortunately not yet functional enough to operate with a cvmfs release manager machine. The Overlay-FS versions in Fedora 23 and Ubuntu 15.10 do work.

Support for extended attributes, such as file capabilities and SElinux attributes.

Support for the SHA-3 derived SHAKE-128 algorithm as an alternative to the aging SHA-1 and RIPEMD-160 content hash algorithms.

As with previous releases, upgrading should be seamless just by installing the new package from the repository. Please take special care when upgrading a cvmfs client in NFS mode. As of this release, we also provide an apt repository. As usual, we recommend to update only a few worker nodes first and gradually ramp up the new version if things turn our all right.
